Precision Machining for Crucial Projects
Some products perform just fine with standard prototype tolerances. We’re here for those that don’t. Our DMU 50 by DMG Mori offers five-axis CNC milling capabilities, enabling our engineers and machinists to create complex shapes in a single setup, and with optimal surface finishes. We also conduct CMM and first article inspection to validate that quality in-house right at our Portland CNC machine shop.
Tell us about your most ambitious CNC machining project, and we’ll help you take it to the next level.
